SRX1400 Services Gateway Routing Engine

The Routing Engine is a PowerPC platform that runs the Junos operating system (Junos OS). Software processes that run on the Routing Engine maintain the routing tables, manage the routing protocols used on the device, control the device interfaces, control some chassis components, and provide the interface for system management and user access to the device.

A pair of USB ports on the Routing Engine accept USB memory cards that allow you to load the Junos OS and perform file transfers.

The Routing Engine also provides the following integrated services:

Central Packet Forwarding Engine Processing (CPP) — This service manages all common form-factor modules (CFM) cards.
System Control— This service provides system management functions such as monitoring of fan trays, and power systems.

Note: The SRX1400 Services Gateway must have a Routing Engine installed in slot RE. The SYSIOC port labeled RE ETHERNET connects directly to the RE Routing Engine slot.
